The Violas, now.

They have to be shifted 30° on the left. What about the room mics? Should I move the R channel a bit to the left, or use the Balance slider to make the L channel stronger than the R?

The first solution would make the stereo field a bit narrower. I've no idea if this also happens when using the Balance control, or the stereo field remains the same, only moved on the same side.

I could finally devoted some time to experimenting. To move the Second Violins to the right here is what works for me:

- Move the Close and Mid mics completely to the right. Don't change the width of the Mid mics.

- Invert the L and R channels of the Room mics. Don't change their width.

- Move the Balance slider of the Room mics to the right, matching the Close and Mid mics.

Paolo

I'm more and more convinced that Second Violins on the left should only be used sparingly, and only if the piece allows for it.

Now, try to do this with that configuration, and try to preserve the original intentions of the composer.

Paolo

When swapping the L and R channels, it's obvious it has to be done for the Room microphones. But what about the Mid mics? They have a very narrow stereo configuration. Should they also have their L/R channels inverted?

Paolo

[Edit] Try it and see, Paolo. Not only are the Close mics almost summed to mono, but also their residual room ambience is so 'polite' and non-assertive that it doesn't seem to interfere at all with L-R-swapped Mains, nor with the HRTF panning and artificial reverb I sometimes add to Mid. But let your ears tell you what's what, when deciding which mics you need to L-R-swap.

My ears say that not swapping the Mid channels is fine, but my mind says otherwise! 😊

But it's probably so subtle that nor me, or my listeners, will be able to ear a difference.

Paolo

You seem to have sorted it then. Never mind that intellectual nagging in the background - it'll soon clear off once you've put your foot down and said this is how it's going to be!

My brain is sending me contrasting ideas.

Reversing channels in Mid mics will make the ambience "straight".

But it will reverse the player's position, that I don't know if would be always desirable.

Paolo

Oops! My comment about the Mid mics being summed almost to mono was incorrect; I was mistakenly thinking of the Close mics - I've just been working with SS Elite and there I have to regard Mid mics as the nearest approximation to Close for the ensemble. In Synchron libraries Close mics are summed almost almost to mono; ensemble Mid mics of course can have considerable L-R contrast. Sorry about that.

So to revisit your question, Paolo, yes of course you could swap Mids too if it's an ensemble and if you can hear distinct azimuth placement (other than by pan and/or balance settings in the  Synchron Player's mixer) as well as L-R stereo contrast in the Mid pair. (Before I begin my spatialisation of a Synchron library I always change all pan and balance settings in the Synchron Player mixer back to default.)

"Straight" and "reversed"? Oh dear, what a situation. Lolol.

I'm not totally sure I can hear a contrast between the reversed Room mics and the non-reversed Mid mics, when moving the 2nd Violins to the right.

However, I've the feeling of doing it right by also swapping the Mid channels. My brain may be tricking my ears, but I feel they sound that bit more coherent.
